egfr.mdrd | R Documentation |
Computes estimated glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) formula.
egfr.mdrd(..., scr.mg.dL, age.yr, is.female, is.black, bun.mg.dL=NULL, albumin.g.dL=NULL, scr.umol.L, scr.conversion.factor = 88.4)

Ignored. This forces all parameters to be named, which is safer. |
scr.mg.dL |
Numeric. Serum creatinine in mg/dL. |
age.yr |
Numeric. Age in years. |
is.female |
Logical. TRUE for females, FALSE for males. |
is.black |
Logical. TRUE if race is 'black', FALSE otherwise. |
bun.mg.dL |
Numeric. Blood urea nitrogen (BUN) concentrations in mg/dL (optional). |
albumin.g.dL |
Numeric. Albumin concentration in g/dL (optional). |
scr.umol.L |
Numeric. Alternative specification of serum creatinine in umol/L. |
scr.conversion.factor |
Numeric. A factor for converting serum creatinine from umol/L to mg/dL. |
All arguments can be vectors. Albumin and BUN are optional. If they are specified, a more elaborate version of the MDRD equation is used.
A numeric vector containing the estimated GFR mL/min.
